Description
Returns the number of bytes available to be read from the ArCOM serial port buffer
Values returned by Arduino remain in a buffer until they are read with MyPort.read()
Syntax
BytesAvailable = MyPort.bytesAvailable()
Parameters
-None-
Returns
BytesAvailable: The number of bytes available to be read.
Example
This example assumes a port has been created with:
MyPort = ArCOMObject('COM3', 115200); % Use your actual port and baud rate
% 1. This loop spams the command window with a message until 10 characters are available in the serial port buffer. Then, the characters are read out and displayed.
while MyPort.bytesAvailable() < 10
disp('Waiting...');
end
disp(MyPort.read(10, 'char'));
